Composition and Inverse

The given functions are:   f(x) = 2x + 5 g(x) = -3 h(x) = 

We have been asked to compute (f - h) (4). (f - h)(4) = f(4) - h(4)

f (4) - h(4) = [2 (4) + 5] - [7 - 4/3]

f (4) - h(4) = 13 - 1 = 12 This is our answer.

Next we are to compose two pairs of the functions into each other. First we will work out (f o g) (x) = f (g(x)) this means the rule of f will work on g. = f (x2 - 3) ...
